Answer:

Area is  220 cm²

Step-by-step explanation:

Firstly divide the polygon into  rectangle and triangle

For rectangle  area

 Area = A  =  L × W = 11 × 18 = 198 cm²

For triangle

Area =  A =  1/2 bh = 1/2 × (15-11) × (18-7) = 1/2 × 4 ×11 = 44/2 = 22 cm²

Add them

     198 + 22 = 220cm²

Which of the following iſ the best statement of the use of the addition rule of probability?
otez555 [7]

Answer:

Option C

Step-by-step explanation:

Addition theory of probability is used to determine the probability for union of two or more sets.

P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.

P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)

for 3 sets

This can be extended to any number of sets

So addition theory has nothing to do with independent events both occurring

Option c is the right answer.
